1929. Serial This ap lication is a division of my application erial No.228,729, filed October 26, 1927.

This invention has for its primary object to provide a novel inkreceptacle and means for detachably securing the receptacle in aprinting machine so that it can be easily and quickly removed wheneverrequired and for any purpose. The invention is particularly adapted forprinting machines which are used as a part of an office equipment forprinting addresses, letters and the like, and in my original applicationand in the accompanying drawing I have shown the invention embodied in amachine having a revoluble signature printing form to which ink isautomatically supplied from the receptacle. Referring to the drawing,

Fig. 1 is a sectional elevation showing the invention and associatedparts of a machine in which it may be embodied.

Fig. 2 is an enlarged'sectional view through the signature roll and inkreceptacle.

In the drawing 3 designates generally a main frame and 4 a signatureframe which is bolted or otherwise rigidly secured to the main frame. Aprinting device in the form of a signature roll 5 is revolubly mountedon shaft 6 and is fully disclosed and claimed in my other divisionalapplication Serial No. 359,197, filed April 30, 1929. The printingdevice or signature roll carries a detachable printing form 7 betweenperipheral flanges 8, 8 which ride on a pair of spaced ink'distributingrolls 9 so that the printingform will contact with said rolls to receive,inkthere from. The rolls 9 have shafts 10 which on gage alined slots 11in the upper end of the ink receptacle 12 and when the receptacle is.removed from the machine these rolls can be lifted out of the slots forrepair 'or replacement. The rolls 9 have tapered ends which cooperatewith the flanges 8 to maintain the 4 rolls in alignment with theprinting form 7. An ink supply roll 13 is mounted in the walls of theink receptacle between and in contact with the distributing rolls tosupply ink thereto. The supply roll is spaced from the signature roll sothat it will not contact there- 228,729. Divided and this applicationfiled May 2. No. 359,775.

with and the arrangement is such that the signature roll will revolveboth of the distributing rolls in the same direction and they willrevolve the supply roll in the same direc tion as the signature rollwhereby a supply of ink is evenly and smoothly transferred from thesupply roll to the distributing rolls and from the distributing rolls tothe signature form. The ink receptacle 12 is provided in its bottom witha groove 14 to engage a support which is in the form of a U-shaped rod15 having out-turned ends 16 engaging the signature frame. A spring 17is attached at one end to a handle 18 on the support 15 and at itsotherend to the signature frame to hold the support in up position. The inkreceptacle has openings 19 to receive pins 20 on the signature rollframe for regis tering and holding the ink rece tacle in proper positionin the machine. rovision 70, is made in a machine of this kind for theadjustment of the signature roll transversely of the'machine to printthe signature at the proper position on the letter sheet and the inkreceptacle being supported and registered and held on the signatureframe will be adjusted with the signature roll to properly registertherewith. To insert the receptacle in the machine the handle 18 isoperated to swing the support downward on its pivots 16, whereupon thereceptacle may be placed in position on the support with the groove 14engaging the support as shown in Fig. 1. Then the handle is released andthe support is swung to up position by the spring 17 engaging theopenings 19 with the pins 20 to register the ink receptacle with thesignal-v ture roll and engaging the distributing rolls 9, 9 with theflanges 8, 8 of the signature roll so that they will distribute ink ontothe face of the type form held between the flanges. The ink receptaclemay be removed from the machine by depressing the support andwithdrawing the receptacle from the support. The receptacle may beprovided with a handle 21 to facilitate inserting the receptacle in themachine and removing it therefrom. A lever 22 is pivoted at 23 on theoutside of the receptacle 12 and it projects into the receptaclebelowthe ink rolls and carries an ab- 100 sorbent pad 24 which isadapted to absorb ink in the well at the bottom of the receptacle and toengage and apply ink to the supply roll 13. The lever has an extension25 which is arranged to be engaged by automatic devices comprising theyoke 26 for intermittently swinging the lever to ink the supply roll asdescribed in my original application.

The invention comprises a simple and convenient means for inking theprinting form which, in the particular embodiment illustrated anddescribed, is a signature form. Any other printing form may besubstituted for the printing form. The supply roll is intermittentlysupplied with ink from the well of the receptacle through the medium ofthe movable absorbent pad 24; and the supply roll evenly applies the inkto the distributing rolls which in turn evenly apply 20" the ink to theprinting form. The receptacle including the supply and distributingrolls and the applying pad with its lever, constitutes a unit which isbodily inserted in the machine and removed therefrom. Provision is madefor easily registering the receptacle with the printing form so that therolls will properly apply the ink to the form. The invention is shown inpart of a printing machine which is fully dis- 30' closed in my originalapplication but it is adapted to other machines and changes in the form,construction and arrangement of parts may be made for this or otherpurposes within the scope of the following claims.
